Patent DE-3029110-A1 (DE)
Title: Digital transmission to several terminals - providing flexibility of framing for signals to terminals and obviating continuous address coding requirements
Inventor: ZENKL GERHARD
IPC: H04J3/24
Filed: 1980-07-31
Abstract: The signal frame structure simplifies the transmission and does not require individual address codes for each terminal. Transmission paths are provided in both directions so that each terminal is able to send as well as receive and the central point (S) acts as an exchange. Signals for all terminals are arranged in a slot of a time frame which is commenced by a start of frame word, each 8 bit slot for each individual terminal follows the start of frame word and is in a determined slot in each frame. The total frame is divided into the sub-frames applicable to the various terminals and has a procedural initial sub-frame which carries the start of frames control word (WO). Information capacity is saved by eliminating individual address codes. Flexibility in the frame structure means that time slots are not dedicated to terminals in a strict order so that they must be used whether carrying information or not.

Title: Shear for cropping a moving rolled strip, in particular a hot-rolled strip
Inventor: MUENKER ERICH
IPC: B23D31/00
Filed: 1981-06-04
Abstract: A shear for cropping the front and rear end of a moving rolled strip has two blade pairs, of which in each case one can be brought into the cutting position for cutting off the front and the rear strip end. A shear of this type is to be improved in such a way that rolled strips of great thickness can also be cropped with it. For this purpose it is proposed to arrange the two blade pairs in an oscillating frame suspended in the shear stand, so that in each case the first blades of both blade pairs are held by a blade support in the oscillating frame, while the other blades of both blade pairs sit on two blade carriages which run in guides displaceably, separate from one another, in the oscillating frame relative to the blade support in the cutting position, which blade carriages can be moved in the cutting direction by means of a common crank drive or eccentric drive via connecting rods relative to the oscillating frame, and so that the two blade pairs can be brought alternatingly into the cutting position by means of adjustment members which are arranged between the crank drive or eccentric drive and the blade carriages.

Title: Device for measuring the cable force of glider launching winches
Inventor: HEIL EDUARD DIPL ING
IPC: B64F1/08
Filed: 1981-07-28
Abstract: The invention relates to a device for measuring the cable force of glider launching winches. The object of the invention is to create a cable force measuring device in the case of which no additional cable wear is produced. It has been found that the behaviour of the contact force of the winch drive units (which is supported at three points such that it can move about the output drive shaft) is proportional to the directly measured cable force. The object is achieved in that the winch drive motor is supported at three or more points such that it can move about the axis of the output drive shaft, of which points a maximum of two are located at a relatively large distance from the axis of the output drive shaft, and in that a force measurement unit is fitted at one of these points, in order to measure the contact force at this point. <IMAGE>

Title: Method of operating a network, in particular a district heating network, to which a pressurised fluid medium is admitted, and arrangement for carrying out the method
Inventor: TRIES DIETER
IPC: F17D3/01
Filed: 1981-08-18
Abstract: So far, in networks to which fluid medium is admitted, pressure-keeping pumps have been used which work with constant delivery capacity during the operating period of the network, even though load fluctuations occur in the network. Allocated to the pressure-keeping pumps are overflow valves which immediately reduce the pressure built up to an unnecessary degree so that an excessive pressure is not admitted to the network. According to the invention, provision is made for the delivery capacity of the pressure-keeping pump (8) and the operating status of the overflow valve (13) to be regulated in accordance with the pressure to be adhered to in such a way that the overflow valve opens only when the delivery capacity of the pressure-keeping pump is reduced to zero in a controlled manner. In this way, energy is not used unnecessarily in order to maintain the pressure in the network. <IMAGE>
